摘要

Background and aims

Plant-soil interactions are crucial in shaping ecosystem functions and have been widely studied. However, the relationships between plant traits and soil microbial communities remain unclear.

Methods

In this study, we collected data on plants, soils, and microbes from 54 sites in temperate grasslands to investigate how soil microbial biomass and diversity vary with climate, soil nutrients, and plant diversity and leaf traits at a regional scale.

Results

The examined factors accounted for 53%, 70%, 28%, and 42% of the variance in fungal biomass, bacterial biomass, fungal richness, and bacterial richness, respectively. The factors influencing microbial biomass significantly differed from those affecting microbial diversity. Microbial biomass was primarily influenced by soil carbon and nitrogen pools, while microbial diversity was jointly affected by climate, soil, and plants. The relative abundance of fungi-to-bacteria ratio decreased with higher plant productivity, diversity, and nutrient availability, suggesting that plant-fungal associations are stronger in less productive, nutrient-poor environments, while bacteria thrive in nutrient-richer conditions.

Conclusion

These findings contribute to a deeper mechanistic understanding of plant-soil interactions and offer practical implications for sustainable grassland ecosystem management.
